Lewis dot arrangement for ammonia is depicted by the outer electrons surrounding the N atom.
The dot point structure in the case of ammonia displays that the nitrogen atom unites 1 pair of electrons with each of the three hydrogen atoms, resulting in a total of 3 joined pairs of electrons.
The ammonia
molecule takes a three-sided pyramid-like shape due to the placement of the outer electrons according to its Lewis Beverage cup arrangement.
In the Lewis dotpoint depiction of ammonia, the nitrogen atom is surrounded by three dots, each representing a pair of shared electrons with a H atom.
